Product Advantages
Micro-stranded construction (single wire down to 0.05mm) ensures a small bending radius and high resistance to repeated flexing, suitable for high-dynamic applications.
Made of high-purity Cu-ETP copper (≥99.95%), low DC resistance, reduced power loss, especially effective for high-frequency current transmission.
Available bare or tin-plated. Tin plating provides effective oxidation and corrosion resistance, and improves soldering reliability.
Strictly manufactured according to GB/T12970.4-2009, ensuring consistency and traceability.
Structure, cross-section, and packing can be adjusted upon request; non-standard solutions are available.

Frequently Asked Questions (FAQ)
Our flexible stranded wires are manufactured using high-purity annealed Cu-ETP copper wires (C11000) with a copper content of ≥ 99.95%, delivering superior electrical conductivity and mechanical ductility.
We provide both bare copper and tin-plated copper finishes. The tin-plated finish significantly prevents surface oxidation, enhances anti-corrosion resistance in mild chemical or humid environments, and improves solderability.
We offer micro-strand diameters including 0.12mm, 0.10mm (AWG38), 0.07mm (AWG41), and ultra-fine 0.05mm (AWG44), specifically designed for high-dynamic flexing and compact bending installations.
To avoid strand damage or premature fatigue failure, keep the minimum bending radius no less than 5 times the calculating outer diameter (OD) of the copper stranded wire.
All products are strictly manufactured in accordance with the GB/T12970.4-2009 standard, accompanied by factory test inspection reports and raw material batch traceability certificates.
Yes. We offer fully customizable conductor structures, cross-sections, and packing formats (rolls, spools, or wooden drums). Custom sample orders and fast turnaround times are available upon request.
